As just described above, my Ashfords average 2.03 cu.ft. per load, so your Princess should scale to about 2.11 cu.ft. per load, with reasonably dense packing. How many loads do you run per day?
Oh, and
@Diabel, I’m loading with 19” - 20” wood, not the recommend 16” - 18”. So, no matter how loose or tight I pack it, I’m still getting 10% more than one cutting the recommended length. That was my primary point, you’re not going to put 2.65 cu.ft. of stacked wood into a 2.65 cu.ft. stove, even if you get dangerously close to the glass.
